Abstract
An informative card such as a baseball trading card is made of sheet metal and is formed so as to be free of sharp edges and pointed corners. Flattened hems around the periphery of the rear side of the card define a raised framing border around indicia which is printed on the rear side. The front side of the card is displaced rearwardly inboard of the hems so as to leave raised peripheral front ledges which define a raised and substantially uninterrupted border around indicia on the front side.
